Part One of many.
-Cardboard boxes: Purchase something you need off Amazon. The box comes free.
Warning: The baby may attempt to ingest the cardboard box. This will not injure him, but it might cause you to despair of his ever making it into an Ivy League college, since he is obviously challenged when it comes to "Food" v. "Not Food."
-Ice cream buckets: Buy ice cream in a giant bucket. Eat all the ice cream. Wash the bucket. It is now a baby toy.
-Peaches: Price for half a peach: Maybe a quarter. Time it kept baby entertained: 23 minutes. That's basically forever in 9-month-old time.
